A painstakingly organized and coordinated process that the palace, the government, the news media, the local authorities, and the queen herself had long prepared goes into motion with the passing of Queen Elizabeth II.
Operation London Bridge, a national memorialization effort, takes place amid the general outpouring of grief. A lot has been meticulously planned, and certain details have already come together.
Charles had already ascended to the throne by the time the world learned of the queen's passing. According to British common law, the heir assumes the throne at the moment of the sovereign's passing.
"God Save the King" will once again serve as the national anthem.
During the first Privy Council, Charles will swear under oath to support the Church of Scotland and announce the date of the queen's funeral.
Later on, he will swear to uphold the established Protestant line of succession in the accession declaration oath. Finally,
he will take the coronation oath, which includes a commitment to maintain Church of England rights and privileges.
Except for one location, all flags will be flown at half-staff through the morning following the funeral for the queen. Flags will be flown at half-staff until the next afternoon on the day Charles is formally declared king.
